Sherman Island is gusting over 20 at daybreak as forecast for the reason that marine layer clouds have crested the East Bay hills. However these clouds will retreat quick to close the Golden Gate and I believe we’ll see Año Nuevo clearing so the winds ought to attain Waddell.
Have a look at the isobars on this picture for this afternoon April 29.
Discover the isobar traces north of Sacramento indicating a low strain space.
Now try the low strain indicated by the isobars in the direction of Bakersfield.
Lastly discover the low strain space east of Stockton.
This implies the strain gradient is fairly evenly break up between Sacramento, Stockton and in the direction of Bakersfield.
That is the perfect state of affairs to carry wind to the shore to most websites from Sherman Island to Crissy to Pt. Isabel and Berkeley to the Peninsula and to Santa Cruz. The one possible low wind exceptions are Larkspur and Tomales.
As a result of all that ocean wind blowing by gaps within the coast vary has to discover a pathway to that low strain. And with this setup a few of it goes from the Nacasio, Petaluma, Muir & Golden Gate gaps previous Pt. Isabel to Sherman. Whereas a few of it goes from the San Bruno Hole by the Altamont Cross and a few by the San Jose and Morgan Hill hole to the Pacheco Cross. And people pathways take the wind to most of our launch websites.
